Smog affects reproductive system: report  

(ECNS) -- In addition to a host of health concerns, smog could also be related to growing problems with infertility, a report says.

The Annual Report on Actions to Address Climate Change 2013, which was co-released Monday by the Chinese Academy of Social Sciences and China Meteorological Administration, listed some negative effects caused by smog.

Smog affects lung functions and structures, damages human immune system, makes chronic diseases severe and respiratory systems deteriorate, reduces reproductive ability and leads to more deaths, scientists said.

The report also noted that smoggy days have increased, particularly in the Yangtze River Delta, a key economic region encompassing Shanghai and parts of Jiangsu and Zhejiang provinces, as well as in southern Guangdong's Zhujiang River Delta, which is adjacent to Hong Kong and Macao. Cities in central and eastern China now have 25 to 100 smoggy days a year, and some even saw more than 100 days, it added.

An 8-year-old girl in Jiangsu province became China's youngest lung cancer patient, reports said, with doctors blaming pollution as the direct cause of her illness.
